Abstract

Abstract: Aiming at 8~12m hard and Extra-thick Coal seam, the fully mechanized top-coal caving mining with super-large mining height，with the cutting height increased, is adopted to enhance the caving performance of top-coal, the paper optimizes the matching parameters of working face equipment, develops a complete set of equipment for fully mechanized top-coal caving mining with super-large mining height of hard coal, researches a strong disturbance and high-efficiency caving mechanism, develops a large volume coal flow transportation system, allocates a Four-level crushing system and memory + remote intervention caving system, etc., have created a safe and efficient intelligent fully mechanized caving face with active perception, automatic analysis, system coordination, which could provide a basic to achieve an annual output of 1.5 Mt thick seam fully mechanized caving mining.
